ecdattr-class

The <code>ecdattr</code> class serves as an object-oriented interface 
between R and ECDB. This class is used extensively during
the <code><a rd-options="" href="/link/bootstrap?package=ecd&version=0.9.2.4" data-mini-rdoc="ecd::bootstrap">bootstrap</a></code> process. A list of light-weight <code>ecdattr</code> 
objects is created first by <code><a rd-options="" href="/link/ecdattr.pairs?package=ecd&version=0.9.2.4" data-mini-rdoc="ecd::ecdattr.pairs">ecdattr.pairs</a></code> function,
then the <code><a rd-options="" href="/link/ecdattr.enrich?package=ecd&version=0.9.2.4" data-mini-rdoc="ecd::ecdattr.enrich">ecdattr.enrich</a></code> function is invoked in parallel to calculate 
additional <code>ecd</code> attributes.

ecdattr

Elliptic lambda distribution and lambda option pricing model
have been evolved into a framework of
stable-law inspired distributions,
such as the extended stable lambda distribution for asset return,
stable count distribution for volatility,
and Lihn-Laplace process as a leptokurtic extension of Wiener process.
This package contains functions for the computation of
density, probability, quantile, random variable, fitting procedures,
option prices, volatility smile. It also comes with sample financial data,
and plotting routines.

The <code>ecdattr</code> class serves as an object-oriented interface 
between R and ECDB. This class is used extensively during
the <code><a rd-options='' href='bootstrap'>bootstrap</a></code> process. A list of light-weight <code>ecdattr</code>
